Description

Technical Field

[0001] The utility model belongs to the technical field of optical lens processing auxiliary equipment, and particularly relates to an optical lens coating fixing bracket. Background Art

[0002] Optical lens coatings are primarily based on the principle of optical interference. By carefully controlling the film thickness and the material's refractive index, light reflection on the lens surface can be reduced, thereby improving light transmittance and image quality. Specifically, the coating thickness is typically designed to be one-quarter of the wavelength of light or an integer multiple thereof. This allows reflected light waves to interfere and cancel each other, minimizing reflectivity.

[0003] The most common method is vacuum evaporation, which involves placing the lens in a vacuum chamber, heating the coating material to evaporate it, and then condensing it into a film on the lens surface. This method is applicable to a variety of materials and is relatively simple to use.

[0004] However, the adhesion of thin films obtained by vacuum evaporation to the substrate is relatively weak. This may cause the film to easily fall off or be damaged during use, thereby affecting the optical performance and service life of the lens. To ensure adhesion, subsequent special spraying treatment is usually required, which increases the complexity and cost of the process.

[0005] To address the aforementioned technical issues, the present invention provides a fixed bracket for optical lens coating. This application utilizes an adjustable bracket structure that allows the bracket to be raised and lowered to achieve coating at varying heights. Compared to conventional substrate structures fixed to the top of a vacuum container, this achieves superior coating results. Furthermore, a flow gap maintained in the bracket's center prevents the majority of the coating material from adhering to a portion of the bracket's surface, further improving the utilization of the coating material and enabling simultaneous double-sided coating. Summary of the Invention

[0006] In order to achieve the above-mentioned purpose, the technical solution of the present utility model is as follows:

[0007] An optical lens coating fixing bracket includes a bracket frame; the bracket frame is a rectangular frame structure, a circular hole is opened in the center of the bracket frame, an outer ring layer is embedded in the inner wall of the circular hole, the outer ring layer is fixedly connected to the inner ring layer by a connecting rod, and a lens to be processed is installed on the inner wall of the inner ring layer through a lens mounting assembly;

[0008] A lifting mechanism is installed at the corner position of the bracket carrier frame.

[0009] Furthermore, the lifting mechanism includes a lifting shaft and a shaft sleeve;

[0010] The end of the lifting shaft is provided with a shaft sleeve, and the shaft sleeve is fixedly connected to the inner wall of the vacuum box;

[0011] The front end of the lifting shaft extends into the mounting hole, and the mounting hole is opened at the corner position of the bracket frame.

[0012] Furthermore, a flow gap is left between the inner layer and the outer layer.

[0013] Furthermore, the mirror assembly includes a supporting slope layer and a lens sleeve; the outer wall of the supporting slope layer is an externally cut slope structure, and the lens sleeve is an internally cut slope structure;

[0014] The outer wall of the supporting slope layer and the outer wall of the lens case form an inclined surface supporting contact structure, and the lens to be processed is mounted inside the lens case.

[0015] Furthermore, the support frame is in an inverted structure through the lifting axis, and the bottom coating end surface of the lens to be processed loaded in the center of the support frame is exposed to the upper end of the external heating crucible.

[0016] The beneficial effects of the utility model are:

DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0024] like Figure 1 、 Figure 2 and Figure 3 As shown, an optical lens coating fixing bracket includes a bracket frame; the bracket frame 4 is a rectangular frame structure, with a circular hole in the center of the bracket frame 4, an outer ring layer 7 embedded in the inner wall of the circular hole, the outer ring layer 7 is fixedly connected to the inner ring layer 8 by a connecting rod 6, and the inner wall of the inner ring layer 8 is installed with a lens to be processed 11 via a mirror assembly 3; the bracket frame 4 is installed with a lifting mechanism at the corners. Among them, the bracket frame 4 serves as the supporting structure of the overall structure, and its own longitudinal height is adjusted by the lifting mechanism to adapt to different coating materials and coating conditions to complete the coating process. The coating on the surface of the lens to be processed 11 is ensured to the greatest extent possible. The circular hole structure in the center of the bracket frame 4 can be used to place the lens to be processed 11. The lens to be processed 11 can be placed in a structure with both the upper and lower sides exposed and the coating completed on both sides through the mirror assembly 3.

[0025] like Figure 1 、 Figure 2 and Figure 3 As shown, the lifting mechanism includes a lifting shaft 9 and a sleeve 1; the end of the lifting shaft 9 is fitted with the sleeve 1, and the sleeve 1 is fixedly docked with the inner wall of the vacuum box; the lifting shaft 9 is adapted to the sleeve 1 to complete the fixing process of the bracket frame 4. During the fixing process, the installation height of the lifting shaft 9 and the sleeve 1 can be pre-adjusted to further adjust the coating processing height of the lens 11 to be processed.

[0026] The front end of the lifting shaft 9 extends into the mounting hole 5, which is provided at the corner of the bracket frame 4. In order to keep the bracket frame 4 in a horizontal state, the mounting holes 5 into which the lifting shaft 9 is inserted are evenly distributed at the corners of the bracket frame 4, thereby achieving force balance.

[0027] like Figure 1 、 Figure 2 and Figure 3 As shown, a flow gap is left between the inner layer 8 and the outer layer 7. The flow gap allows the evaporated coating material to adhere to the back of the lens 11 to be processed as quickly as possible at multiple angles.

[0028] like Figure 1 、 Figure 2 and Figure 3 As shown, the mirror assembly 3 includes a supporting slope layer 10 and a lens case 12. The outer wall of the supporting slope layer 10 has an circumscribed slope structure, while the lens case 12 has an inscribed slope structure. The outer wall of the supporting slope layer 10 and the outer wall of the lens case 12 form an inclined support contact structure, and the lens case 12 is internally mounted with the lens 11 to be processed. The circumscribed slope structure of the supporting slope layer 10 and the inscribed slope structure of the lens case 12 ensure balanced support.

[0029] like Figure 1 、 Figure 2 and Figure 3 As shown, the support frame 4 is in an inverted structure through the lifting shaft 9, and the bottom coating end face of the lens 11 to be processed loaded in the center of the support frame 4 is directly exposed to the upper end of the external heating crucible.
